Conjunctival Congestion

Conjunctival congestion (red eye) is dilation of conjunctival vessels, a nonspecific sign of conjunctivitis, irritation, allergy, or subacute inflammation. It must be distinguished from ciliary/limbal flush (keratitis/iritis/glaucoma) which requires urgent evaluation. Treatment: identify and treat the cause (antibiotics/antihistamines/lubricants); avoid redness-reliever overuse; urgent ophthalmology if pain/photophobia/vision loss.
